Abstract (en)

[origin: EP0905453A2] The secondary heat exchanger connects thermally a user water conduit to the hot water mains. A hot water accumulator compensates for the time loss caused by the heating of the primary heat exchanger. The hot water accumulator (35,31) is in close thermal contact with the plates of the secondary heat exchanger (30), forming a structural unit with it.
